I am not totally sure, but based on some reading I did there is a compatibility issues between Powershell 7 and ExchangeOnline, even though its almost 1 year post, but not sure if MS fix it or not.

I have the same case, and I am using Powershell 5.1 to manage Exchange Online, as it seems that Powershell Core is not compatible with the module.
even in Windows Event Log I have the following Warning:

farismalaeb is correct, the ExO V2 module doesnt support PowerShell 7/Core yet. A preview version is available and GA should follow in the coming weeks/months.
Hi VasilMichev , i am facing the same issue to use powershell script 7 to connect to ExchangeOnline.
Just wondering if you know what is current progress ? Thanks.
- Powershell 7 is not compatible with EXO. Must use powershell 5 or 6.
- For those (like me) finding this in 2022 or later, current versions of ExchangeOnlineManagement are compatible with PowerShell Core. To fix this issue, install ExchangeOnlineManagement 2.0.4+
Open a command prompt with admin rights and enter:
Install-Module ExchangeOnlineManagement -Force
This installs the latest version alongside your current instance.
